A lication fi led bece'm'nr 27,1922; Serial no. 609,247.

To. all toizom it may concern:

Be it known that I, HENRI GnIvEL, c 1t1 zen of the French Republic,residing at'Guebof which the relative positioncan be adj usted, areinserted before the needle combs, the object being on the one hand toobtain a more advantageous construction by reducing the needle-combs,and on the other hand to increase the production. Another feature of theimproved machine according to the invention consists therein, that theupper needle comb-set is hinged about the driving end of the worm devicein such away that the proper meshing of the screw-spindle and therelative position of the cams carried thereby remain unaltered, wherebyafter raising and securing the upper needle combset out of the way bymeans of a suitable device provided for the purpose, fibrous material ofany kind whatever may be drawn by means of a single needle combjset: insuch a case it is suflicient to adjust the needlecyl.inders which, asstated above, are according to the invention arranged so as to. permitsuch adjustment. Adjustment is however also obtained throughthe'drawingcylinder, to the extent of about 1/25 of an inch in heightabove the level of the needle combs of the lower set. This latteradjustment of the drawing-cylinder from the upper position for drawingwith two needle comb-sets to the lower position for drawing with asingle needle comb-set is caused by an automatic tightenting of theendless belt.

An embodiment of the improved drawingmachine according to the inventionis, by way of example only, illustrated by the accompanying drawing,wherein:

Fig. l is a partial side-elevation showing two intermeshing rows ofneedle combs forming part of a so-called gill intersectingdrawing-machine.

Fig. 2 is a similar view, but with the up per needle-comb-set in theraised position.

:As maybe seen from the drawing, on "the front worn'rspmdles afaremounted 'gear-.

wheels 6 having teeth with heads rounded as shown in the" direction oftheir width, so as to allowthe- -upper needlecomb-set 0,'of which theframe d is hinged or pivoted about the trunnion e, to be raised as shownby Fig. 2, without the position of the cams being altered "thereby.These cams are mounted in known manner on the screwspindles a and f inthe case of a double row of needle combs or on one of said spindles inthe case of a single row of needle combs. g, it and z indicate theneedle-cylinders, of which one i can be adjusted by means of thelever-arm In pivoted about the centre of h, and can be maintained inposition by means of the lever-arm-J. The needle-cylinders, of which theinterchangeable needle-number fittings vary from rough for g to mediumfor h and fine for i, constitute a preparationmachine which permits ofthe needle combs at being kept finer.

WVhen it is desired to work with a single needle comb-set, the upperneedle comics 0 are raised. The amplitude of this movement is set bymeansof a suitable guide-member which in the embodiment illustratedconsists of a curved arm n pivoted at 0 and having a notch which, whenthe upper needle comb-set is raised, comes to bear on a projecting pin pof the frame 9 of the lower needle comb-set.

In the position Fig. 2 the needle combs m can be taken out for cleaningpurposes.

The adjustment of the drawing-cylinder 2% takes place through automatictightening of the endless belt 2 by the pressure-hook a pivoted aboutthe centre of t. For this purpose, a pres'su.relever u is pivotallyconnected to said pressure-hook as shown at 1",

and the said pressure-lever u on the one hand is subjected to theinfluence of a pressure-spring a and an adjustment-screw w, and on theother hand exerts a pressure on a roller 51 mounted on the pulley-shafta: and thus causes the tightening of the belt 2.

I claim:

1. In a drawing-machine of the kind set forth comprising a frame andupper and lower intersecting needle comb-sets mounted therein, aplurality of cooperating needlecylinders positioned before comb-sets,and means for adjusting the position of said cylinders in relation toone another.
